Alternative definition : BIOCARTA: Receptors in the TNF receptor family are associated with the induction of
apoptosis, as well as inflammatory signaling. The Fas receptor (CD95) mediates apoptotic
signaling by Fas-ligand expressed on the surface of other cells. The Fas-FasL interaction
plays an important role in the immune system and lack of this system leads to autoimmunity,
indicating that Fas-mediated apoptosis removes self-reactive lymphocytes. Fas signaling
is also involved in immune surveillance to remove transformed cells and virus infected
cells. Binding of FAS to oligomerized FasL on another cell activates apoptotic signaling
through a cytoplasmic domain termed the death domain that interacts with signaling
adaptors including FAF, FADD and DAX to activate the caspase proteolytic cascade.
Caspase-8 and caspase-10 are first activated and then cleave and activate downstream
caspases, and a variety of cellular substrates, leading to cell death. Caspases cleave
nuclear lamins, causing the nucleus to break down and lose its normal structure. They
also cleave DFF, inducing cleavage and degradation of the genome. Other caspase substrates
are involved in cytoskeletal structure, cell cycle regulation and signaling pathways.
Activation of JNK kinase, activation of Jun, and production of ceramide may also play
roles in Fas-mediated apoptosis. Activation of Fas-mediated apoptosis is opposed by
I-FLICE and FAP. Viruses and tumors may escape immune surveillance in part through
suppression of Fas-mediated apoptosis. (This definition may be outdated - see the
